Detailed Description
The invention is described in further detail below with reference to the following detailed description and accompanying drawings:
as shown in fig. 1, a large-scale purse seine culture system comprises a culture purse seine 1, a first sinking purse seine sinker device and a second sinking purse seine sinker device 3.
The cultivation purse seine comprises an upper net line 1.1, a lower net line 1.3, a netting 1.2 positioned between the upper net line and the lower net line and a buoyancy device connected with the upper net line.
The first path sinking bottom purse net sinker device comprises a first iron chain 2 which is arranged on the lower net line and extends along the lower net line.
The second sinking purse seine sinker device comprises a strip-shaped air bag 3.1 which is positioned outside the breeding purse seine and extends along the lower net line, a net sleeve which is sleeved outside the strip-shaped air bag, a water pressure trigger exhaust valve 3.4 which is arranged on the strip-shaped air bag, a second iron chain 3.2 which is positioned in the strip-shaped air bag and extends along the lower net line, a plurality of distance control rods 3.3 which are sequentially distributed along the length direction of the first iron chain, and a strip-shaped connecting net piece 3.5 which is used for connecting the net and the net sleeve and extends along the length direction of the lower net line. The buoyancy of the strip-shaped air bag is larger than the gravity of the second iron chain.
The length of the distance control rod is 1-2 meters, and the length of the distance control rod is 1.8 meters in the embodiment. The distance control rods are distributed at equal intervals along the length direction of the first iron chain. One end of the distance control rod is hinged on the first iron chain or connected with the first iron chain through a connecting rope, and the other end of the distance control rod is connected with the net cover.
As shown in fig. 1 and 2, the number of the water pressure triggered exhaust valves in the present embodiment is multiple, and the water pressure triggered exhaust valves are equidistantly distributed along the length direction of the strip-shaped airbag. The water pressure triggering exhaust valve comprises a main cylinder body 3.41 and a valve sleeve 3.45 which are positioned on the outer side of the strip-shaped air bag, an exhaust pipe 3.44 which is connected with the inner cavity of the main cylinder body and the inner cavity of the strip-shaped air bag, a cylinder piston 3.42 which is arranged in the main cylinder body in a sliding mode and a valve sleeve piston 3.46 which is arranged in the valve sleeve in a sliding mode. The exhaust pipe is connected with the strip-shaped air bag in a sealing way. The inner diameter of the main cylinder body is larger than that of the valve sleeve. The first end of the main cylinder is provided with a communication hole 3.43. The second end of the main cylinder body is communicated with one end of the valve sleeve. A pre-tightening compression spring 3.47 is arranged in the main cylinder body and between the cylinder piston and the second end of the main cylinder body. An annular limiting block 3.48 is arranged in the main cylinder body, and the cylinder body piston is positioned between the annular limiting block and the first end of the main cylinder body.
When the cylinder piston abuts on the first end of the main cylinder: the exhaust pipe is located between the cylinder piston and the second end of the main cylinder.
When the cylinder body piston is abutted to the annular limiting block: the exhaust pipe is located between the cylinder piston and the first end of the main cylinder.
During sinking of the breeding seine (before sinking to the seabed):
as shown in fig. 1, the breeding purse net sinks under the action of a first iron chain;
the second iron chain floats upwards under the buoyancy action of the strip-shaped air bag and is pulled by the distance control rod;
when the first iron chain is close to the seabed, the inner diameter of the main cylinder body is larger than that of the valve sleeve, so that under the action of the water pressure of external seawater, the acting force of the pre-tightening compression spring is overcome, the cylinder piston moves towards the second end of the main cylinder body until the cylinder piston abuts against the annular limiting block, and at the moment, gas in the strip-shaped air bag is gradually discharged through the exhaust pipe, the main cylinder body and the communicating hole.
As shown in fig. 3, after the first iron chain sinks to the seabed, the lower net line of the cultivation purse net can be ensured to be attached to the seabed surface because the first iron chain is a continuous iron chain and can be attached according to the seabed surface;
more importantly: when the first iron chain sinks to the seabed, the gas in the strip-shaped air bag is gradually discharged, and when the gas in the strip-shaped air bag is discharged to a certain degree, the second iron chain sinks under the action of gravity; in the process of sinking the second iron chain, the distance control rod drives the strip-shaped air bag and the second iron chain to rotate downwards in the direction far away from the first iron chain around the first iron chain, therefore, when the second iron chain sinks to the seabed and is attached to the surface of the seabed, the second iron chain can not only cooperate with the strip-shaped connecting net piece to form a second blocking line on the surface of the seabed, and can ensure that the second iron chain has enough space with the first iron chain (the space between the second iron chain and the first iron chain is controlled by the length of the distance control rod), so that if the first iron chain is settled on a bulge with a hollow structure or other bulge structures on the seabed, the second iron chain can be crossed over the convex structures, the convex structures are positioned at the inner side of the second iron chain, thereby further effectively avoiding the formation of a passageway between the bottom of the aquaculture purse net and the surface of the sea bottom, and effectively avoiding the problem that fishes in the aquaculture purse net are drilled out from the net bottom.
